The “cost of quality” isn’t the price of creating

a quality product or service. It’s the cost of

NOT creating a quality product or service.

Every time work is redone, the cost of quality

increases. Obvious examples include:

The reworking of a manufactured item.

The retesting of an assembly.

The rebuilding of a tool.

The correction of a bank statement.

The cost of quality is generally classified into

four categories:

1.External Failure Cost

2. Internal Failure Cost

3. Inspection (appraisal) Cost

4. Prevention Cost

Cost associated with defects found after the

customer receives the product or service.

Example: Processing customer complaints,

customer returns, warranty claims.

Cost associated with defects found before the

customer receives the product or service.

Example: Scrap, rework, re-inspection,

material review, material downgrades.

Cost incurred to determine the degree of

conformance to quality requirements

(measuring, evaluating or auditing).

Example: Inspection, testing, process or

service audits.

Cost incurred to prevent poor quality.

Example: New product review, quality

planning, supplier surveys, process reviews,

quality improvement teams, education and

training.
